To all whom t may concern:

Be it linovin that l, FRANK F. SoRnNsnN, a citizen of the United States, residing at the city oit Philadelphia, county of Philadelphia, and IState oil Pennsylvania, have invented certain new and useful lmprovements in Roller-Bearings, of Which the following` is a specification.

rlllhis invention yhas relation to the styleof roller bearing),- shown and described in U. ld. Letters Patent #986,453 and has for its leading object to so improve the struc` ture oit such type of bearing; as to enhance the commercial value thereof. Other and further objects' relate to the provision of general details oi construction and to the arrangement and combination of parts tor attaining the advantages sought by the leading1 object.

rl`he invention will be claimed at the en d hereof but Will be rst described in connection ivith the embodiment of it chosen from other embodiments for 'the salie illustration in the accompanying` drawings, in Which-there is shown principally in section7 one-half of a roller bearing embodying features of the invention.

ln the drawings l and 2 designate inner and outer rings arranged one Within the other and they are concentric in respect to the common axis c--a. The adjacent faces ot such rings are properly inclined with respect tothe common axis a-Ha to form a race-Way for accommodating` a circle of conical or taperebearings. @ne of these rin in the present instance the inner ring7 is provided with a pair of spaced shoulders 4 and '5. rllhe inner tacos t5-5' oi these shoulders are disposed at' right angles to the axis man 6 designates one ot a circle ot tapered rollers the larger or inner end ot' Vwhich is dat as at (3 and is disposed at right angles to the axis 72H7). rlhe smaller or outer-end of such roller is of substantially conical configuration as at 6. Fixed upon the shoulders 4C and 5 are annular members 'l' and 8 which function as retaining means for the roller. @t these members that designated 7 is provided With a beveled Specification of Letters Patent.

portion 9 the plane of which parallels the plane of the roller face 6. The beveled portion extends beyond the inner face oi shoulder t so that While the flat end of a roller revolves free thereof a roller is retained against removal from the race-Way thereby. lt is to be noted that the peripheral edge 10 of a roller is the only point oit contact at its iiat end. and that such conw tact point is with the iiat inner face of shoulder 4f. The member 8 is beveled as at l1 which bevel extends beyond the fiat face of shoulder 5 and serves as a bearing; surface for the tapered end oli' a roller. The member 7 may if desired be shaped and proportioned as shown at l2 in the dravvings to 'function as a dust excluder. The part l2 comprises an annular iianged portion of a diameter substantially equal to the greatest diameter of outer ring 2.

Experience demonstrates that a bearing constructed in the manner described is not only comparatively inexpensive to manutacture but is ecient in practice and commercially considered overcomes all the ob jectionable features present in the type of bearing before alluded to.

What l claim is l. A roller bearing comprising the combination oi' inner and outer rings havingopposed taper roller races whereof one is provided With a pair of spaced shoulders the inner face of each of Which is flat and is termed at right angles to the bearing axis, a circle of taper rollers each having` one flat end and a substantially conical end arranged between said races and between said shoul ders, the peripheral edgge of a roller having a one point contact with the flat face oit' a shoulder and retc initie,V rings having),1 beveled ends fixed with respect tosaid shoulders, a beveled'portion being projected beyond a hat face of a shoulder.

2. A roller bearing` as described in claim l, characterized by the outermost retaining ring being` provided with an annular flanged portion of a diameter substantially equaling the greatest diameter of said outer ring.
